Reaction scheme:
0x58bGwhPS

Synthesis:
1. A solution of 1H-pyrrolo[2, 3-b]pyridine-3-carboxylic acid (0.49 g, 3 mmol), oxalyl chloride (0.6 mL, 7.2 mmol), and DMF (1 mL) in dichloromethane (20 mL) was stirred for 20 min.
2. The mixture was evaporated and then redissolved in methanol (20 mL) and stirred for 40 min.
3. The mixture was evaporated and then extracted with ethyl acetate.
4. The organic phase was washed with saturated sodium bicarbonate solution and dried with Na2SO4, and the solvent was removed in vacuo to yield the white solid (0.36 g, 68%).
5. A solution of Step 4 (0.36 g, 2 mmol), potassium t-butoxide (0.27 g, 2.4 mmol), and 1-bromo-5-fluoropentane (1.6 g,9.5 mmol) in THF (20 mL) was stirred for 24 h.
6. The mixture was extracted with ethyl acetate.
7. The organic phase was washed with brine and dried with Na2SO4, and the solvent was removed in vacuo.
8. The residue was purified by silica gel chromatography with stepwise gradient elution of n-hexane/ethyl acetate (3:1–2:1–1:1, v/v) to yield the white solid (0.35 g, 65%).
9. A solution of step 8 (0.35 g, 1.3 mmol) and 6 mol/L sodium hydroxide solution (10 mL) in methanol/THF (2:1,v/v, 15 mL) was stirred for 1.5 days.
10. The mixture was evaporated, added to water, and then washed with ethyl acetate.
11. A solution of 1 mol/L hydrochloric acid was added to the aqueous phase, and the mixture was extracted with ethyl acetate.
12. The organic phase was washed with brine and dried with Na2SO4, and the solvent was removed in vacuo to yield the white solid (0.39 g, quant.)
13. A solution of step 12 (0.39 g, 1.3 mmol), oxalyl chloride (3 mmol), and DMF (1 mL) in dichloromethane (12 mL) was stirred for 10 min.
14. The mixture was evaporated and then redissolved in dichloromethane (10 mL).
15. Cumylamine (2 mmol) and triethylamine (0.5 mL) were added to the solution and stirred for 15 h.
16. The mixture was evaporated and then extracted with ethyl acetate.
17. The organic phase was washed with 0.1 mol/L hydrochloric acid solution, saturated sodium bicarbonate solution and brine, and then dried with Na2SO4, and the solvent was removed in vacuo to yield the white solid (0.37 g, 77%).

Просто умножавайте всичко с 370х (1000g/0,37g = 370 съотношение) като "основно правило".

Разбира се, сигурен съм, че някои разтворители позволяват по-висока плътност на сместа, напр. няма да ви трябва 370х повече етилов ацетат, но бързо ще забележите, когато разтворът е пренаситен, но имайте предвид, че повече топлина позволява по-голямо насищане (не знам защо).

Благодаря за това, че го оценявам. Но аз съм начинаещ и се нуждая от конкретна информация, за да избегна грешки.

Някой може ли да качи видеоклип с урок? Аз съм начинаещ и няма да искам да знам всяка стъпка (включително необходимото оборудване). Ще бъда благодарен Благодаря много

Здравейте, това аналог на 5F-КУМИЛ- ПЕГАКЛОН (5F-SGT-151) ли е ?
Възнамерявате ли да качите и негов синтез? Това би било повече от интересно.
Благодаря ви за огромната работа.

О, току-що разбрах, че основата на 5F-SGT-151 съдържа и цял 3-ти бензолен пръстен. Качвам номенклатурата.
Чудех се дали 5F-SGT-151 може да бъде изработен и вместо 1-бромо-5-флуоропентан да се използва като опашка,
бихме могли да използваме 1-бромо-6-флуорохексан. Това би ли ни дало още по-голям афинитет към рецепторите/ефекти?

Според тези данни бих казал "да", но това е само хипотеза.

Да, мисля, че това ще е достатъчно. Имам още един въпрос. Кои са най-силните канабиноиди?

Адб-Чминака и някои класически видове ноиди.

Здравейте,
Пиридинът алтернатива ли е на калиевия терцбутоксид в тази реакция?

I am interested in the synthesis of 5F-adb is there a simple reliable recipe?
